But I don't want it to do the actual install.  I just want it to go 
through the motions and check to see that IF it actually were 
installed and the repro in my yum.conf is used, that all dependencies 
are satisfied, and to report what had to be added to meet any 
currently unsatsified dependencies.

Why do I want to do this?

Curiosity?

Fear?

Doubt?

Gee.  I Scalix v 10 now comes with JRE and Tomcat to install (if you 
want them for the features they add to Scalix).  But Scalix is set 
for a RedHat install.  Perhaps there are java things that are in 
RedHat (because it costs money?) that are not automagically in 
Centos.  If so, then I would get unmet dependencies.

Also Scalix installs these within its installer, and somehow (I AM 
going to ask them), that don't think they use yum, just expect all 
dependencies to already be met.  So I COULD meet the dependencies 
separately, then let Scalix install these tools.

Sound 'extreme'?  Hey, I am not proficient in this stuff, and 
anything like this that increases my understanding with not too much 
pain, should be at least tried....
